When engineers figured out how to do that two decades ago, they enabled complex tests to be performed with tiny "lab on a chip" technology. But until now, there has been no way to accurately measure the size of the tiny vessels they created. Now,scientists at the National Institute of Standards and Technology have found a potential solution to this longstanding manufacturing issue.http://phys.org/news/2015-04-technique-volumes-key-lab-chip.html

Biochemistry Fri, 16 Aug 2013 09:40:01 EDTnews295863649Lab-on-a-chip technology gets a flexible upgradeMicrofluidic devices move liquids through tiny, hair-sized pathways carved into glass slides and have distinct advantages over traditional laboratories when it comes to medical diagnostics. At these reduced scales, fluid transport is enhanced by factors such as diffusion and high surface-to-volume ratios, making testing procedures much faster. By constructing parallel arrays of microfluidic pathways, researchers are working to produce 'lab-on-a-chip' technologies that allow multiple biological tests to be performed using just a drop of blood or urine. In a development that promises to make lab-on-a-chip devices more portable and economic to construct, Yo Tanaka from the RIKEN Quantitative Biology Center and colleagues have now produced a new type of microfluidic control valve that takes up significantly less space on a microchip than existing approaches.http://phys.org/news/2013-07-lab-on-a-chip-technology-flexible.html
Analytical Chemistry Fri, 12 Jul 2013 10:20:01 EDTnews292839778An all-glass lab-on-a-chipLab-on-a-chip devices are microfluidic cells that incorporate pipes, reaction vessels, valves and a host of other implements typically found in laboratories. These components are typically carved into a flat plastic plate smaller than a credit card to enable efficient processing of microliter-volume samples. The use of plastic, however, has several drawbacks that could be remedied by using glass. Unfortunately, glass chips have proved difficult to fabricate due to their fragility. Yo Tanaka from the RIKEN Quantitative Biology Center has now developed a reliable and durable system for incorporating glass microfluidics into lab-on-a-chip devices.http://phys.org/news/2013-07-all-glass-lab-on-a-chip.html

Nanophysics Thu, 01 Sep 2011 06:27:00 EDTnews234077185Smooth operators: Teflon microfluidic chips(PhysOrg.com) -- The growing number of research and development efforts focused on microfluidics speaks to the technology&#146;s promise of a potentially broad range of applications, largely in highly-integrated single-chip medical devices. However, the materials currently used to fabricate these labs-on-a-chip and other microfluidic devices have significant limitations, including absorption of small nonpolar and weakly polar molecules, adsorption of biomolecules, and the material&#146;s molecules leaching into the microfluidic channel. The good news is that researchers have overcome these obstacles using microfluidic channels made entirely of Teflon, which supports cellular activity similar to that found in current materials. Moreover, whole-Teflon microchannels have gas permeability levels that permit cells to be cultured in-channel for extended periods of time.http://phys.org/news/2011-05-smooth-teflon-microfluidic-chips.html

General Physics Wed, 18 Nov 2009 11:00:02 EDTnews177761689'No muss, no fuss' miniaturized analysis for complex samples developedThe goal of an integrated, miniaturized laboratory analysis system, also known as a "lab-on-a-chip," is simple: sample in, answer out. However, researchers wanting to use these microfluidic devices to analyze complex solutions containing particulates or other contaminating materials often find that the first part of the process isn't so easy. Effective sample preparation from these solutions can be laborious, expensive and time-consuming, involving complicated laboratory methods that must be performed by skilled technicians. This can significantly diminish the benefits associated with using miniaturized analytical techniques. Recent work at the National Institute of Standards and Technology could help change that.http://phys.org/news/2009-11-muss-fuss-miniaturized-analysis-complex.html
